摘　　要：铌矿属重要的战略矿产资源,我国多数铌矿存在储量少、品位低、分布不均匀等问题。该文以洛南县刘家沟铌矿为研究对象,依托陕西省地质勘查基金项目开展研究,铌矿床赋存在该区宝山沟组一套碱性火山岩内,着重介绍了该区的区域地质背景及矿区地质背景,总结了控矿因素,分析了矿床成因,对国内其他类似矿床有着借鉴意义。Niobium ore is an important strategic mineral resource.Most of China’s niobium deposits face challenges such as limited reserves,low grade,and uneven distribution.This study focuses on the Liujiagou Niobium Mine in Luonan County,conducted under the Shaanxi Geological Exploration Fund project.The niobium ore deposit is hosted within a suite of alkaline volcanic rocks of the Baoshanxi Formation in the area.This paper primarily introduces the regional and mining area geological settings,summarizes the controlling factors,analyzes the ore genesis,and provides insights applicable to similar domestic deposits.
